4clalms. (cl. 12s- 194) This invention relates -to the oven doors ofsoldered 0r Spot welded to the inner side of stoves and ranges and meansfor hlnging said the Wall |6-v doors te the lower edge of the ovenopening, and Mounted in the side edges oi the door between among theobjects of the invention are; to prothe Walls I6 and I7 are a Delrefbex-like hinge vde a hinge construction wherein practically leaves 22that constitute the movable leaves 0f 5 all of the hinge elements areconcealed, to prothe Oven dOOr hinge Structure. Mounted in and vide ahinge construction which will permit the extending between the sideWalls 0f said hinge door to be readily applied to and removed fromleaves (See Fig. 4) are hinge pintles 23, Which the stove body by themere manipulation 0f a, are adapted to enter and seat in the slots Il ofi0 pair of hinge pintle latches and without requirthe bracket I3. Thepintles 23 are removably 10 ing the removal of the pintle or any otherhinge locked in the $10158 I4 by latches 24 pivOted at 25 elements, toprovide a, hinge construction that on the brackets I3 and having ontheir forward will avoid any chang or marring of the enamel ends Curveddepending fingers 26 that hOOk over of the stove front in the region ofthe hinge, te the pintles 2.3, as Clearly ShOWn in Fig. 4- The providean improved spring-actuated device for inner wall I'I of the door hasslots 21 and the 1li supporting the door in fully lowered 0r open p0..top walls of the hinge leaves 22 have slots 23 siton and assisting theclosing movement, and to registering With the Slots 27 that permit theprovide a hinge construction especially weil brackets and latches toenter the lower` edge poradapted for use on double-walled insulateddoors. tlOn 0f ille dOOr and engage With the Dintles 23. An illustrativeembodiment of the invention is The Channel frame members, such as l0 and20 shown in the accompanying drawing, in which- II, are usually ofporcelain, and the brackets Fig, 1 is a, perspective view 0f a lowercoi-ner I3 and latches 24 project from the bar l2 through portion of theoven opening and door, showing vertical slots 29 (Fig. 1) in thehorizontal frame the latter in fully lowered or open position.

An important advantage of the described strucapplication and removal ofthe door. To apply the door it is necessary only to raise the latches24, enter the hinge pintles 23 in the bracket slots I4, 'lower thelatches, and then pull forward the links 3| and engage their hooks 33with the pins it is necessary only to disengage the hooks 33 from thepins 30, raise the latches 2|, and then withdraw the door from the stovebody.

Variations and modifications in the details oi structure and arrangementmay be made withi the scope and coverage of the claims.

I claim:

1. In a stove, door frame and a door having spaced outer and innerwalls, of means for removably hinging said door at its lower edge to thelowerV horizontal member of the frame comprising forwardlyI pro-'jecting brackets on said lower frame member having slots open at theirforward ends, box-'like hinge leaves mounted in the side edges oi saiddoor between said walls; hinge pntles mounted 1n and extending betweenthe side walls oi said leaves and adapted to enter and seat in saidslots, and latches pivotally connected to saidlower frame member adaptedto engage with. said pntles and lock the latter in said slots; said doorand hinge leaves having suitably located slots to permit said bracketsand latches to engage with said pntles.

2. In a stove, the combination with an oven door frame and a door havingspaced outer and inner walls, of means for removably hinging said doorat its lower edge to the lower horizontal 30. To 'emove the door,

the combination with an oven member of the irame comprising forwardlyprojecting brackets on said lower frame member having slots open attheir forward ends, box-like hinge leaves mounted in the side edges ofsaid door between said walls, hinge pntles mounted in and extendingbetween the side walls of said leaves and adapted to enter and seat insaid slots, and latches pivotally connected to sa'id lower frame memberadapted to engage with said pintles and lock the latter in said slots;the inner and lower edge walls of said door and the top walls of saidhinge leaves having suitably located slots to permit the entrance ofsaid brackets and latches into engagement with said pntles.

3. In combination with the subject-matter defined in claim 1, pinsmounted in and between the side walls of the hinge leaves in rear of thehinge pintles, links mounted to slide inwardly andoutwardly along theside walls of the oven and having on their forward end hooks removablyengaged with said pins, and springs exerting an inward pull on saidlinks; said door and hinge leaves having suitably located slots topermit said hooks to be engaged with and disengaged from said pins.

4. In combination with the subject-matter dened in claim 1; pins mountedin and between the side walls of the hinge leaves in rear of the hingepintles, links mounted to slide inwardly and outwardly along the sidewalls of the oven and having on their forward ends depending hooksremovably engaged with said pins, pull springs anchored to the sidewalls of the oven and exerting an inward pull on said links, and stopson said links serving through contact with the door frame to limit thedown swing of the door to a substantially horizontal position; said doorand hinge leaves having suitably located slots to permit said hooks tobe engaged with and disengaged from said pins.
